From now on, cloudy and rainy days are expected to continue from Tohoku to Kyushu, and it seems there will be many unrefreshing weather days. In Hokkaido, the forecast is for relatively stable and mostly sunny days.



Tomorrow, the 15th (Tuesday), the autumn rain front will gradually move south, and the front's activity is expected to intensify. Rain will fall over a wide area from Tohoku to Kyushu. In some localized areas, the rain is likely to become heavy and may be accompanied by thunder. Please be very careful of road flooding and water accumulation in low-lying areas.

After that, the main island of Japan will continue to be influenced by humid air, and cloudy or rainy days are expected nationwide. Even if there are sunny periods during the day, the weather will be changeable due to the humid air, so please pay attention to changes in the sky. Because of the long-lasting rain so far, the ground may be loose in some places, increasing the risk of landslides even with a little rain. Please stay away from dangerous slopes and cliffs.

Also, there is a tropical depression in the southern sea area of Japan, which is expected to take a westerly path and travel south of the main island. It is not expected to develop into a typhoon yet, but it could significantly affect the weather in the future.

This weekend from the 19th (Saturday), Silver Week will start, but depending on the development and path of the tropical depression and the movement of the autumn rain front near the main island, the weather could change significantly. If you have plans during the holiday, be sure to check the latest weather updates regularly.

Because of this, around Honshu, the range of rain is likely to expand from northern to western Japan on the Japan Sea side. Especially in Tohoku and Hokuriku, it is expected to be a path for developing rain clouds associated with the autumn rain front, and there may be places with heavy rain accompanied by thunder. Please be careful and stay alert for landslides, flooding in low-lying areas, and sudden rises in rivers.



On the Pacific side of western Japan, it may be sunny during the day in some areas, but there may also be localized rain or thunderstorms. Be careful of heavy rain in a short time, lightning, and strong gusts such as tornadoes.
In Okinawa, rain clouds are likely to develop due to moist air, resulting in weather with intermittent rain.

In Kanto-Koshin, many places will be sunny from the morning, making it a good day for doing laundry. Temperatures will be higher than the previous day, the 13th, and the lingering summer heat will be intense, with a forecasted 35C in Kumagaya (Saitama Prefecture).

In the mountainous areas of Kanto, there is a possibility of localized thunderstorms in the afternoon. Pay attention to changes in the sky.
